Introducing Fantom Finder — passive-radar verification of cooperative broadcasts. $500 of off-the-shelf SDR hardware listens for radar reflections off existing TV broadcast towers and cross-checks every Remote ID drone broadcast, AIS ship transponder, and ADS-B aircraft squitter against what physics actually shows. Mismatches auto-broadcast as Cursor-on-Target XML to ATAK / WinTAK / Delta in sub-millisecond. Use cases in strait of Hormuz and on the battlefield to detect dangerous signals.
